使用iTextsharp创建PDF时，在页脚添加pdfpTable
在我的Asp.net应用程序中，我必须生成PDF所以我使用 Itextsharp 4.0 这是免费的开源，我引用this来设置听众/页脚在生成的PDF上，
但现在我的问题是我无法在页脚中添加 pdfPtable ，是否有任何建议如何在页脚插入表格？
代码Page_Load
CreatePDF("Invoice", dtaddproduct, "Prince", "1313", "04/09/2013","4000");
在 CreatePDF 方法中，我正在调用
TwoColumnHeaderFooter PageEventHandler = new TwoColumnHeaderFooter();
writer.PageEvent = PageEventHandler;
之前document.Open();
自定义HeaderFooter代码（TwoColumnHeaderFooter）：
public override void OnStartPage(PdfWriter writer, Document document)
{
base.OnStartPage(writer, document);
Rectangle pageSize = document.PageSize;
if (Title != string.Empty)
{
cb.BeginText();
cb.SetFontAndSize(bf, 15);
cb.SetRGBColorFill(50, 50, 200);
cb.SetTextMatrix(pageSize.GetLeft(40), pageSize.GetTop(40));
cb.ShowText(Title);
cb.EndText();
}
if (HeaderLeft + HeaderRight != string.Empty)
{
PdfPTable HeaderTable = new PdfPTable(4);
HeaderTable.DefaultCell.VerticalAlignment = Element.ALIGN_MIDDLE;
HeaderTable.TotalWidth = pageSize.Width - 80;
HeaderTable.SetWidthPercentage(new float[] { 45, 45, 45, 45 }, pageSize);
PdfPCell HeaderLeftCell = new PdfPCell(new Phrase(8, HeaderLeft, HeaderFont));
HeaderLeftCell.Padding = 5;
HeaderLeftCell.PaddingBottom = 8;
HeaderLeftCell.BorderWidthRight = 1;
HeaderTable.AddCell(HeaderLeftCell);
PdfPCell HeaderRightCell = new PdfPCell(new Phrase(8, HeaderRight, HeaderFont));
HeaderRightCell.HorizontalAlignment = PdfPCell.ALIGN_RIGHT;
HeaderRightCell.Padding = 5;
HeaderRightCell.PaddingBottom = 8;
HeaderRightCell.BorderWidthLeft = 1;
HeaderTable.AddCell(HeaderRightCell);
cb.SetRGBColorFill(0, 0, 0);
PdfPTable table = new PdfPTable(3);
table.TotalWidth = document.PageSize.Width - document.LeftMargin - document.RightMargin;
PdfPCell cell = new PdfPCell(new Phrase("Header spanning 3 columns"));
cell.Colspan = 3;
cell.HorizontalAlignment = 1; //0=Left, 1=Centre, 2=Right
table.AddCell(cell);
string billNumber = HttpContext.Current.Session["billlno"].ToString();
string billDate = HttpContext.Current.Session["billdate"].ToString();
string TotalRate = HttpContext.Current.Session["totalhours"].ToString();
string customerName = HttpContext.Current.Session["customername"].ToString();
table.AddCell("Date: " + billDate);
table.AddCell("Bill No: " + billNumber);
Chunk ck=new Chunk("one\ntwo\nthree\nfour");
ck.SetBackground(Color.RED);
Phrase p = new Phrase();
p.Add(ck);
PdfPCell cl = new PdfPCell();
cl.AddElement(p);
cl.BackgroundColor = new Color(0, 150, 0);
table.AddCell(cl);
table.AddCell("Total : "+TotalRate);
table.AddCell("M/s : "+customerName);
table.AddCell("Col 2 Row 2");
table.AddCell("Col 3 Row 2");
table.AddCell("Col 1 Row 3");
table.AddCell("Col 2 Row 3");
table.AddCell("Col 3 Row 3");
table.WriteSelectedRows(0, -1, document.LeftMargin, document.PageSize.Height - 36, writer.DirectContent);
}
}
public override void OnEndPage(PdfWriter writer, Document document)
{
base.OnEndPage(writer, document);
int pageN = writer.PageNumber;
String text = "Page " + pageN + " of ";
float len = bf.GetWidthPoint(text, 8);
Rectangle pageSize = document.PageSize;
cb.SetRGBColorFill(100, 100, 100);
cb.BeginText();
cb.SetFontAndSize(bf, 8);
cb.SetTextMatrix(pageSize.GetLeft(40), pageSize.GetBottom(30));
cb.ShowText(text);
cb.EndText();
cb.AddTemplate(template, pageSize.GetLeft(40) + len, pageSize.GetBottom(30));
cb.BeginText();
cb.SetFontAndSize(bf, 8);
cb.ShowTextAligned(PdfContentByte.ALIGN_RIGHT,
"Printed On " + PrintTime.ToString(),
pageSize.GetRight(40),
pageSize.GetBottom(30), 0);
cb.EndText();
}
public override void OnCloseDocument(PdfWriter writer, Document document)
{
base.OnCloseDocument(writer, document);
template.BeginText();
template.SetFontAndSize(bf, 8);
template.SetTextMatrix(0, 0);
template.ShowText("" + (writer.PageNumber - 1));
template.EndText();
}
已编辑的代码（TwoColumnHeaderFooter）：
我编辑放在OnEndPage上的代码。在这里我遇到同样的问题，看看截图，你会发现一个链接更多信息正在显示，而不是我也用代码编写的表。 帮助请
